I don’t usually have the need to make mug cake, since I have a keto home bakery and we always have chocolate lala cupcakes on hand in the freezer. However, sometimes I sell out and want just want a few bites of yummy keto chocolate mug cake.

That’s why I keep a few bags of single serving chocolate cake ingredients on hand. I suggest you do the same, if you’re not interested in making a whole dozen at any one time.

Low Carb Chocolate Mug Cakes Tested Several Times

How I Developed this Recipe

One day last year my assistant and I made several different versions, taking notes, and tasting. We were scribbling, switching out ingredients, changing heating times. Reducing the fat from one tablespoon to two teaspoons made the difference! I also prefer using avocado or olive oil instead of butter, as the cake will be more moist and it’s also easier.

We tried to make an almond flour only cake, but for that, one teaspoon of coconut flour made a difference. What we really liked was adding a sprinkling of choc zero sugar free chocolate chips on top. It needed to be moist, chocolatey and low in carbs.

What is a Mug Cake?

It’s a single serving cake made in a mug, small bowl, or ramekin in the microwave (or oven). It can be grain free (like this one made with almond flour), sugar free (I’m using Swerve), and can be made keto friendly.

Can you Bake a Mug Cake in Oven Vs. the Microwave?

The answer is a resounding yes. The thing is people typically make a mug cake on the fly satisfying a chocolate craving and want to stick it in the microwave for 60 seconds. However, if you have 14 more minutes to stick it in the oven, it’s a little better.

I tested both ways by make a double batter and dividing between two large ramekins. I baked for 15 minutes at 350 degrees F (180 C). Baked cake will always be better than microwaved cake. Both were good. Both were just slightly denser than a sponge cake but not quite like a brownie cake. I am insistent on only using 1/2 of an egg because otherwise I think the cake is too eggy.

How Can I Top a Low Carb Chocolate Mug Cake?

There are several easy ways to top this cake:

  • Sprinkling of Sugar Free Confectioner’s (Swerve)
  • Whipped Cream
  • Whipped Cream with Berries
  • Fast Ganache: Heat 1/4 cup heavy cream with 2 tablespoons sugar free chocolate chips for ganache or make this recipe and keep in fridge for up to two weeks. Can also be frozen.
